The subarticular crescents is a way of describing how the damage looks like in the image (like a crescent moon under the affected articulation)
Avascular necrosis means the tissue (in this case the bone) has died because of poor blood supply to the area. After a while the bone can collapse. If this condition is not treated, the joint will deteriorate and this will become severe arthritis.

General & Family Physician Dr. Olubusola Brimmo's  Response
This means that the blood supply to your femoral head, (which is part of your hip joint) is impaired, this may lead to pain and eventually collapse of the head which may lead to arthritis which may lead to more pain, and the eventual need for hip replacement.You need to discuss this with your orthopedic surgeon
